Phthalate-free plasticizer preparation comprises: 1-98 wt.% of at least one alkyl sulfonic acid aryl ester (I); and 2-99 wt.% of at least one diol dibenzoate (II) and/or at least one dicarboxylic acid dibenzyl ester (III). Phthalate-free plasticizer preparation comprises: 1-98 wt.% of at least one alkyl sulfonic acid aryl ester of formula (R 1>-SO 2-O-R 2>) (I); and 2-99 wt.% of at least one diol dibenzoate of formula (R 3>C(O)O-Y 1>-O(O)CR 4>) (II) and/or at least one dicarboxylic acid dibenzyl ester of formula (R 3>CH 2O(O)C-Z-C(O)OCH 2R 4>) (III). R 1>1-20C-alkyl, preferably 10-20C-alkyl; R 2>-R 4>phenyl (optionally substituted by 1-4C-alkyl or halo); Y 1>an optional ether group containing 2C alkyl, preferably optionally up to five ether group containing 2-10C-alkyl; and Z : cyclic or polycyclic 2-10C-hydrocarbon, preferably succinic acid, glutaric acid, adipic acid, pimelic acid, suberic acid, azelaic acid or sebacic acid. An independent claim is included for a plastic comprising the phthalate-free plasticizer preparation. |
